The Advanced Medium Combat Aircraft (AMCA) is an Indian single-seat, twin-engine, all-weather fifth-generation stealth, multirole combat aircraft being developed for the Indian Air Force and the Indian Navy. AMCA is designed as a single-seat, twin-engine combat aircraft. The AMCA is currently the only 5th generation fighter under development in India.
- The AMCA Mark 1 will come equipped with 5th generation technologies.
- The AMCA Mark 2 will have the incremental 6th generation technology upgrades.

DESIGN:-
The AMCA is designed with shoulder mounted diamond shaped trapezoidal wings, a profile with substantial area-ruling to reduce drag at transonic speeds, and a stabilator V-tail with large fuselage mounted tail-wing. Flight control surfaces include leading and trailing-edge flaps, ailerons, rudders on the canted vertical stabilizers, and all-moving tailplanes; these surfaces also serve as air brakes. The cockpit features a single seat configuration which is placed high, near the air intakes and wings of the aircraft to provide good visibility to the pilot with a single bubble canopy. A leading-edge root extension (LERX), which is a small fillet, is situated on the front section of the intake and wings of the aircraft. It has a typically roughly rectangular shape, running forward from the leading edge of the wing root to a point along the fuselage. The aircraft features a tricycle landing gear configuration. The weapons bay is placed on the underside of the fuselage between the nose and main landing gear. The AMCA is designed to produce a very small radar cross-section, to accomplish this it features "S-shaped" air-intakes to reduce radar exposure to the fan blade which increases stealth, uses an internal weapons bay and features the use of composites and other materials. The flight control surfaces are controlled by a central management computer system. The AMCA design has inherent radar stealth, achieved through twin-tail layout, platform edge alignment and serration, body conformal antenna and low intercept radar, diverterless supersonic inlet (DSI) with serpentine ducts which conceal engine fan blades, internal weapons bay and extensive use of composites in airframe. It will also use radar-absorbent materials wherever necessary.
AVIONICS:-
The AMCA is expected to have distributed passive sensors with Artificial intelligence (AI) assisted multi-sensor data fusion to increase situational awareness and to work in tandem with the advanced electronic warfare (EW) suite onboard AMCA. The AMCA has a distributed processing system employing fast processors and smart subsystems. The AMCA will also have an integrated vehicle health monitoring system which works on sensor fusion. AMCA will be equipped with a larger and powerful variant of the Uttam AESA Radar which will use gallium nitride (GaN) technology. It will be mounted on a mechanically steerable mount. An onboard condition monitoring system is also planned to be included in the AMCA. The platform will be equipped with a quadruple digital fly-by-optics control system using fibre optic cables to reduce weight, increase the rate of data transfer and reduce electromagnetic interference.
PROPULSION:-
The AMCA is to be powered by two afterburning turbofan engines. The plan is to equip General Electric F414 afterburning turbofan engine on AMCA Mark-1, while a more powerful joint venture (JV) engine is planned for AMCA Mark-2.
